Abstract

Patente de Invenção: <B>"CATALISADOR E PROCESSO PARA CONVERSãO DE METANOL A HIDROCARBONETOS"<D>. São fornecidos um catalisador e um processo para a conversão de metanol ou de dimetil éter a um produto que contenha C~ 2~ e C~ 4~ olefinas. O catalisador compreende um material cristalino poroso que tem um Parâmetro de Difusão para 2,2-dimetilbutano de 0,1-20 s^ -1^ quando medido a uma temperatura de 120°C e uma pressão de 2,2-dimetilbutano de 60 torr (8 kPa). Além disso, o catalisador é caracterizado por uma estabilidade hidrotérmica tal que, após tratamento com vapor d'água do catalisador a 1025°C durante 45 minutos em vapor d'água de 1 atmosfera, o catalisador exibe uma atividade de conversão de metanol de pelo menos 50% quando em contato com metanol a uma pressão parcial de metanol de 1 atmosfera, uma temperatura de 430°C e 0,5 WHSV. O material cristalino poroso é de preferência uma zeólita do poro médio, particularmente ZSM-5, que contém fósforo e que foi tratada rigorosamente a uma temperatura de pelo menos 950°C.Invention Patent: <B> "CATALYST AND PROCESS FOR CONVERSION OF METHANOL TO HYDROCARBONS" <D>. A catalyst and a process for converting methanol or dimethyl ether to a product containing C ~ 2 ~ and C ~ 4 ~ olefins are provided. The catalyst comprises a porous crystalline material that has a Diffusion Parameter for 2,2-dimethylbutane of 0,1-20 s ^ -1 ^ when measured at a temperature of 120 ° C and a pressure of 2,2-dimethylbutane of 60 torr (8 kPa). In addition, the catalyst is characterized by a hydrothermal stability such that, after treatment with water vapor from the catalyst at 1025 ° C for 45 minutes in water vapor from 1 atmosphere, the catalyst exhibits a methanol conversion activity of at least minus 50% when in contact with methanol at a methanol partial pressure of 1 atmosphere, a temperature of 430 ° C and 0.5 WHSV. The porous crystalline material is preferably a mid-pore zeolite, particularly ZSM-5, which contains phosphorus and which has been rigorously treated at a temperature of at least 950 ° C.
